Thanks for the detailed feedback! I kind of rushed you into the deep end for this demo. I’ll make sure to have a puzzle to explain that you need momentum to hit objects next time.
I think the puzzles just south of the /agdg/ logo are the toughest in the demo: so many permutations with the ice blocks. This whole demo was a bit of a rush job so I don’t think I balanced it properly: the alternate route going right of the /agdg/ logo is much easier so gg on getting through hard mode.
